Flipping the Switch Without Lifting a Finger

With the adoption of new state and local energy standards aimed at reducing global energy consumption, virtually every non-residential building will be facing more stringent lighting control requirements. Whether these standards are based upon ASHRAE Standard 90.1, the International Energy Conservation Code (IECC), or a particular state-developed provision, meeting the requirements with a flexible, easy-to-use, and economical lighting control system may seem impossible. Nevertheless, through the aid of advancing technology a lighting control system can be achieved that eliminates energy waste, while creating a cost-effective and user-friendly environment. With few exceptions, both ASHRAE 90.1 and the IECC state that the... Read More

Six Feet Under: A Geothermal Systems Overview

Due to the current global energy pinch, alternative and more environmentally friendly methods of heating and cooling our buildings have been developed. One such system, the geothermal heat pump system, uses an alternate and renewable energy source – the Earth – as a means of heating and cooling a building. Our planet stays at roughly 55 degrees year round and has an almost unlimited ability to absorb, store, and give up thermal energy. Therefore, geothermal heat pump systems use the Earth as a huge heat sink to pull heat from and reject heat to. “…the geothermal heat pump system uses... Read More
